Hello

when trying to open a .pptx in Aspose Slides v22.01 i get the following exception:

com.aspose.slides.exceptions.NotImplementedException: The method or operation is not implemented
…
Wrapped by: com.aspose.slides.PptxReadException: The method or operation is not implemented
at com.aspose.slides.alk.do(Unknown Source)

the original file is this one: Content not found | LimeWire

the code open the file im using is this:

Presentation presentation = new Presentation("testdoc.pptx");

presentation.save("testdoc.pptx", SaveFormat.Pptx);

I know the issue is related to the waterfall chart because if I remove it it works, however I couldnt find more specific details

Hope you can help

Jose

It seems that you are encountering a NotImplementedException when trying to load a .pptx file in Aspose Slides v22.01, specifically related to a waterfall chart in your presentation. This issue has been recognized, and a ticket has been created for it in the issue tracking system.

The good news is that this problem has been addressed in a later version of Aspose.Slides for Java (version 22.2). I recommend upgrading to this version or a newer one to resolve the issue you are facing. You can find the latest version and the release notes on the Aspose website.

Here’s a brief outline of what you can do:

  1. Upgrade to Aspose.Slides for Java 22.2 or later.
  2. Test your presentation again after the upgrade.

You can download the latest version from the following link: Aspose.Slides for Java Downloads.

If you continue to experience issues after upgrading, please feel free to reach out for further assistance.

I tried upgrading the version as the automatic reply suggested… my license lets me upgrade up to 22.7 but the issue remains

@jroldan1,
I’ve reproduced the error in Aspose.Slides for Java 22.1 and 22.7 but the exception does not appear in version 25.3. We recommend using the latest version of Aspose.Slides for Java.
